Backup Power using CBC Energy Storage Technology!

In this demonstration, Capacitech Energy uses our CBC technology to provide backup power to a personal AC unit. The CBC's were able to power the fan for ~30 seconds after the fan was unplugged from the wall! When the power source is disconnected, the CBC discharges to power the fan inside the personal AC unit.

This is a fantastic demonstration as it shows how the CBC can be built directly in a power cord to provide coverage during power fluctuations.

The CBC could discretely provide backup power to a variety of devices such as Wi-Fi routers, cable boxes, game consoles, IT equipment, electric bikes, or even RAM cards... Stay tuned for more demonstrations!

Design FAQ

Q: How much power does the fan draw?

A: The fan draws an average of 1.5W.

Q: What is the input voltage from the source?

A: Any 5 watt iPhone charger can be used as a 5V source.

Q: How many CBC cells are needed in what connection for this demonstration?

A: Because the input voltage is 5V, four CBC cells are needed connected in series. Each CBC cell is rated to 1.6V. By adding four cells in series, the combined CBCs are rated to 6.4V. To provide additional back up power, 10cm cells are used and are connected in parallel.

Q: How long will the CBC provide backup power for?

A: It depends on the power drawn by the load. In this demonstration, the CBC’s provide about 30 seconds of backup power. We found that by adding another strand of four series connected 10cm cells, an additional 15 seconds can be supported.

CBCs Powering LEDs

We at Capacitech Energy, LLC (Capacitech) are often asked how we know the length of the cell is proportional to energy storage. We know this is true because: 

  1. The equation for capacitance is proportional to surface area. Therefore, if you have two devices with the same diameter but one is twice as long, it will have twice the surface area and twice the capacitance.

  2. We have done a lot of testing on these devices. One of the tests are called a GCD curve where we charge and discharge the CBC devices at a constant/controlled current such as 10mA. The longer CBC devices take longer to charge and discharge. A CBC device that is twice as long as another CBC device will take twice as long to discharge too.

  3. From experiments like the one described below!

This video features two 5cm long CBC devices connected in series and two 10cm long CBC devices connected in series. We charge them up side by side and discharge them both into an individual LED. The two 5cm CBC last about 4mins while the 10cm devices lasted about 8min. 

Performance of components used: 

Two 5cm CBC devices in series = 0.5F @ 3.2V                                                                  Two 10cm CBC devices in series = 1F @ 3.2V 

CBC Powers DC Electric Motor & Fan

The CBC technology is capable of performing like a super capacitor or a more traditional capacitor. It all depends on the length of wire being used. Here, we connected four CBC devices that are 10cm in length in parallel for 8F of capacitance at 1.6V. The materials used in this demonstration are shown in the image below. 

CBC Fan Demo

We charged 10cm long CBC devices connected in series for 1 minute using a DC source providing constant voltage. 

The CBC was then discharged in a standard DC electric motor rated to 9V. 

As shown in the video, the CBC was able to provide about 1minute of power to the load proving it is a capacitor by nature in the form of a cable.

The CBC could discretely provide backup power to a variety of devices such as Wi-Fi routers, cable boxes, game consoles, IT equipment, electric bikes, or even RAM cards.
